Ummm. Yes. I made vtkTextActor use display coordinates by default because
there are more TextMapper/Actor2D pairs in vtk code than there were
ScaledTextActors (only vtkCaptionActor2D used it in vtk itself) - thus it'd
be a bit less painful to change them to the new textactor.

vtkScaledTextActor used to initialize itself with NormalizedViewport coords,
so one or the other had to give :(

Berk has removed the warning from vtkScaledTextActor, so everyone can just
use it and forget about any changes. We don't have to remove it if everyone
likes it!
